| ☜ | Effect on $X and $YDraft MDC Standard | ☞ | ||||
Below follows a list of control-functions (X3.64) or controlmnemonics (M[UMPS]) that have an effect on the special variables $X or $Y or both. Since some definitions in X3.64 are fairly open-ended, the exact effect may be implementation dependent in some cases. In section 3.4 these open-ended definitions are listed resolution of possible ambiguities are stated.
The relevant controlmnemonics are:
| /CBT(n) | $X | |
| /CHA(x) | $X | |
| /CHT(n) | $X | |
| /CNL(n) | $X, $Y | |
| /CPL(n) | $X, $Y | |
| /CUB(n) | $X | |
| /CUD(n) | $Y | |
| /CUF(n) | $X | |
| /CUP(y,x) | $X, $Y | |
| /CUU(n) | $Y | |
| /CVT(n) | $Y | |
| /HPA(x) | $X | |
| /HPR(n) | $X | |
| /HTJ | $X | |
| /HVP(y,x) | $X, $Y | |
| /IND | $Y | |
| /NEL | $X, $Y | |
| /PLD | $Y | |
| /PLU | $Y | |
| /REP(n) | $X, $Y | |
| /RI | $Y | |
| /RIS | $X=0, $Y=0 | |
| /VPA(y) | $Y | |
| /VPR(n) | $Y |
The control-function REP repeats the previous character or function as many times as indicated by its argument. Hence, the side-effects of this function do not depend on this function itself, but rather on the character or function that is being repeated.
